一、引言 一九六四年春,在鉴定南岭地区的一些矿物标本时,发现一种棕红色的矿物,经研究认为是一种新的含锂、钙、镁和氟的亚砷酸盐矿物,并根据其产于南岭地区命名为南岭石。近年,有机会重新获得同一产地的另一些标本,进一步研究证明,它确系一种新的亚砷酸盐矿物。 南岭石的发现,不仅具有矿物学意义,并可能提供新的结晶学知识。更重要的是本矿 I. INTRODUCTION In the spring of 1964, during the identification of some mineral samples from the Nanling area, a reddish-brown mineral was found which, according to the research, was regarded as a new arsenite mineral containing lithium, calcium, magnesium and fluorine , And according to its production in the Nanling area named Nanling stone. In recent years, another opportunity has been given to retrieve other specimens of the same origin, and further studies have shown that it is indeed a new arsenite mineral. The discovery of Nanling Stone not only has mineralogical significance, but also may provide new crystallographic knowledge. More important is the mine
